I've got a pair of padded under shorts but they're only padded in the crotch area and its the seat bones where I'm getting the pain. Wondering if its possible to get shorts with padding in this area
Shorts will have pading in all the right areas. These pants of yours sound, er, a bit pants..!
If you're wearing baggy shorts without an in-built liner, buy some regular lycra cycling shorts and wear them underneath the baggies. If doing this, buy bib shorts, which have straps to go over your shoulders, as these are a more comfortable fit.
If the shorts are comfortable (i.e. not chafing), and you're still having problems, then move on to a new saddle. Specialized do offer an arse-measuring service, which ought to help narrow it down.
Make sure your saddle is level (pointing up or down is not good) and then properly adjusted in forwards/backwards moveemnt on the rails so that your sit bones are on the wide bit at the back.
